Always use approved parts when performing  maintenance and repairs. Make sure that replacement parts 
meet or exceed the origin

al parts’ specification. 

 

Only  authorized,  trained,  and  competent  individuals  are  allowed  to  perform  installation,  operation, 
maintenance, and repair. 

 

Completely isolate incoming and outgoing pressures to the generator, and make sure to depressurize the 
service/repair section prior to performing any mechanical work, including changing the filters.  The nitrogen 
generator’s exhaust gas and/or any venting gas must be vented to the outside or to a large, well-ventilated 
room to avoid suffocation due to lack of oxygen. 

 

Safety glasses should be worn if the cabinet door is open while the machine is operating. 

 

Use ear protection when the equipment is operating. 

 

WARNING:  Pressurized  gases  are  contained  within  the  generator,  the  receiver,  and  product  tanks.    Pressurized 
gases are dangerous and may cause injury or death if handled or used inappropriately. 

 

 

Never  allow  pressurized  gas  to  exhaust  from  an  unsecured  hose.  An  unsecured  hose  may  exhibit  a 
whipping action,  which can cause serious injury.  If a  hose should  burst during use, immediately close  all 
isolation valves if it is safe to do so and power down the unit. 

 

Never disable or bypass any safety relief valves. 

 

Always make certain that the nitrogen generator is disconnected from the supply power prior to performing 
any electrical work. 

NOTE: Always following local and site safety regulations in conjunction with this manual. Warning: 

 

This manual must be read in its entirety prior to installing and operating the 

BrewBlast™ 70CPH to prevent 

accidents and damage to the 

BrewBlast™ 70CPH. 

 

Contact your supplier if you detect a problem that you cannot solve with the help of this manual. 

 

Only use the 

BrewBlast™ 70CPH in accordance with its designed purpose.  

 

Only  service-engineers  that  are  qualified  to  work  on  electric  and  pneumatic  equipment  are  allowed  to 
perform  the  installation,  maintenance  and  repairs.  Unqualified  people  are  not  allowed  to  repair  the 
equipment.  

 

Do not tamper or experiment with the equipment, or exceed the technical specifications.

Air Compressor: 

The  air  compressor  is  designed  internally  to  the  cabinet  and  features  an  engineered  dampening  system  to 
reduce vibration and noise throughout the cabinet. It is an oil-less compressor with a pre-filter attached to the air 
input.  The  recommended  replacement  on  the  pre-filter  is  1,000  run  hours  or  1  year  (whichever  comes  first). 
Dirtier  environments  may  require  more  frequent  filter  replacements.  Consult  your  supplier  for  a  more  frequent 
filter maintenance schedule if the generator is installed in a dirty environment.
